Both molecules were approved based on small numbers of patients (tepotinib pivotal trial: NCT02864992) due to the significance of the response in trials. MET is a great case study for small molecules being approved before large molecules for a surface receptor – anti-MET antibodies were expected to lead in this area and were initially thought to be more clinically advanced. MET antibodies surprisingly failed to demonstrate efficacy in later trials, which may be due to a number of factors including the fact that antibodies can in certain cases be agonists for their…
